MOVABLE SIGN.

SPECIFICATION forming part of Letters Patent No. 412,394, dated October8, 1889.

Application filed Tune 26, 1889. Serial No. 315,623. (No model.)

'of thecar will cause an active vibration of the sign.

The invention consists in the various features of improvement more fullypointed out in the claims.

In the accompanyingdrawings, Figure 1 is a face view of my improvedsign. Fig. 2 is a rear view thereof; and Fig. 3, a longitudinal sectionon line w Fig. 2.

The letter a represents a suitable figure or v sign, which is to attractthe eye by its vibration. It is fixed upon a pivot inpassing 4through.the sign-board c, and is protected, if

desired, by the glass d. The board c is slotted, as at c', at a placeback of sign a, and here the sign is provided with a pin a', enteringthe slot. It will be seen that by imparting reciprocating motion to thispin the sign a will be vibrated on its pivot.

The mechanism for imparting motion to pin a is as follows: To the rearside of board c there is secured between a pair of bearingplates e,screwed to the board c, a pivot f. Upon this pivot there turns a leverg, which is weighted at g'. I prefer to make the lever of the form shownin Fig. 2, in which it is shown to be open or cut out at the center,thus concentrating its maximum weight at its weighted section. Abovethis weighted section the lever g is provided with an arm g2. To thisarm there is secured one end of a very delicate coiled spring h,theother end of which is attached to the fixed support h. The lever gisprovided, furthermore, with a second arm g3, to the free end of which isconnected one end of a rod 1l, the other end of which engages pin a. Itwill be seen that the joint action of the spring and weight will causethe lever g to be oscillated upon its pivot f by the motion of the car.This motion will, by arm g3, rod and pin a', be transmitted to the signa.

' Thus a very slight motion of the car will cause an active vibration ofthe sign.

1. The combination of a slotted back plate with a sign pivoted thereto,a lever g,also pivoted thereto and connected to .the sign, and with aspring h, by which the free end of the lever is suspended, the sign andthe lever turning on different pivots, substantially as specified.

-neoting thelever to the sign, substantially as specified.
